<font color="#67854E">**Question**</font>: What is Lely milk day production and how can I view it in DairyComp?

<font color="#67854E">**Answer**</font>: Lely milk day production is an **adjusted total milk yield** value calculated by the Lely Horizon system. It factors in milking visit dates, times, and animal physiological factors to provide a more refined daily milk production figure for each cow. This value differs from the raw milk weight totals traditionally displayed in DairyComp.

To allow producers to monitor this specific Lely-calculated performance metric, DairyComp now imports and stores Lely milk day production values. Once your DairyComp is updated to the relevant build <u>and configured for the Lely milk interface</u>, this feature will automatically appear on the **Lacations** tab of CowCards; no additional end-user action is required except to [create the additional Lely milk items](docId\:ykhT5f7URu2Oo8GWCuaJo).

## Benefits of Lely Milk Data

For dairy producers utilizing both Lely Horizon and DairyComp, maintaining consistent and accurate cow performance data is crucial. Previously, farmers often observed discrepancies between the adjusted milk day production values displayed in Lely Horizon and the raw total milk weights recorded in DairyComp. This feature bridges this gap and provides a more comprehensive view of individual animal performance.

## View Lely Milk Data

Lely adjusted milk weight data is updated throughout the day and is viewed from the **Lactations** tab on the CowCard:

::Image[]{src="https://api.archbee.com/api/optimize/3h8pSJcGUXEi4HGCCYPTA/Z8YSXO8s4yZ86q2ngegj9_lelytab.png" size="32" width="1268" height="1020" darkWidth="1268" darkHeight="1020" position="flex-start" showCaption="false"}

1. The row for Lely milk data is labeled **Lely** and is located below the **Total** row. If you hover over the word Lely, a tool-tip pops up revealing that it's for Lely adjusted milk weight.
2. One DairyComp item, called **LELY1**, will be created during the next milking session import into DairyComp. LELY1 corresponds to the **Today** column on the tab (i.e., the current day).
3. In this example, a full 7 days of Lely data is shown. You'll need to [create additional items](docId\:ykhT5f7URu2Oo8GWCuaJo) (LELY2, LELY3, etc.) to monitor a full 7-day history of Lely milk production data.

## Create Additional Lely Milk Data Items

While DairyComp supports storing up to 7 days of Lely milk day production values, additional items for previous days (e.g., LELY2, LELY3, etc., up to LELY8) must be manually created to display this historical data.

Follow the steps below to continue:

1. In the command line, enter ALTER\2 to display the **Item Definitions** window.
2. Select **Add \[Ins]** to add a new item to DairyComp.
3. In the window that displays, enter the following properties for each new item:

| ****  | **** | **** | **** |                                 |
| ----- | ---- | ---- | ---- | ------------------------------- |
| LELY2 | 120  | 2    | 16   | 2nd Lely Adjusted Milk Weight   |
| LELY3 | 120  | 3    | 16   | 3rd Lely Adjusted Milk Weight   |
| LELY4 | 120  | 4    | 16   | 4th Lely Adjusted Milk Weight   |
| LELY5 | 120  | 5    | 16   | 5th Lely Adjusted Milk Weight   |
| LELY6 | 120  | 6    | 16   | 6th Lely Adjusted Milk Weight   |
| LELY7 | 120  | 7    | 16   | 7th Lely Adjusted Milk Weight   |
| LELY8 | 120  | 8    | 16   | 8th Lely Adjusted Milk Weight   |

4. Click **OK** to save the newly created item.

**NOTE:&#x20;**&#x54;he Lely milk day production items cannot be used in the Parlor Performance and Parlor\O report module.

## Run Reports Containing Lely Milk Day Production Data

Once you have created your Lely milk day production items, you can use them in reports and lists. Below are some example commands you can run to create useful reports.

**Summary of daily milk**

This report shows averages of daily milk production by milking pens:

`SUM DMLK1 LELY1 MDEV DIM WMDEV WMLK1 BY PEN FOR MPENS>0 DMLK1>0\F`

Testda&#x79;**&#x20;production summary**

This report shows averages of test day production by milking pens:

`SUM DMLK1 LELY1 WMLK1 PCTF RELV 305ME DIM LACT FOR MPENS>0 BY PEN`

**Fresh cow list**

This report examines fresh cows during their first 60 days of milking. In this case, you would look for drops in milk production between the recent days to identify potential problem cows for further review. You would also look for cows with a significant jump in milk production (e.g., 10 pounds):

`LIST PEN ID LACT:1 DIM LHEVT LHREM DMLK3:5 DMLK2:5 DMLK1:5 LELY1 MKDAT:5 BFDAT:5 FOR DIM=1-60`

:::hint{type="info"}
**NOTE:&#x20;**&#x53;ince items are customizable, not all of the items shown in the examples may be available for your DairyComp system. For instance, LHEVT (last event) and LHREM (last event remark) used in the "fresh cow list" command above are customized items.
